To all whom it may concern.

Be it known that I, ORLO A. LUoAs, a citizen of'the United States, and aresident of Richwood, county of Nicholas, and State of West Virginia,have invented a new and 11m proved Box-Gluing Apparatus, of which thefollowing is a full, clear, and exact description.

This invention relates to an apparatus for gluing of paste board boxes,and has for an object the gluing in place of the covers of paste boardboxes, said apparatus being adapted to operate on boxes of varioussizes.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which it is understood that the drawingsillustrate only one form of the invention, and in which- Figure l is anelevation of the apparatus with parts broken away to disclose theconstruction.

Fig. 2 is a fragmentary top view of the apparatus.

Fig. 3 is a fragmentary elevation of a portion of the apparatus.

Fig. 4 is a detail view of the unlocking cam.

Referring to the accompanying drawing by numerals, 10' indicates avertical center pole to which is secured a plurality of lower radiatingribs or struts 11. The pole 10 is provided at its lower end with a pin12 which engages a step bearing 13, and a similar pin 14 engages anupper step bearing 15. Ball bearings 16 are provided between the lowerend of the pole 10 and the bearing 13 so that said pole with itsradiating ribs may be easily rotated.

An outer annular channel bar 17 is supported by the struts 11, and aninner annular channel bar 18 is also supported by said struts, the twochannel bars 17 and 18 having their flanges 19 turned adjacent and beingconcentrically spaced apart. The chan nel bars 17 and 18 are adapted tosupport a plurality of spiders 20 to each of which is secured a boxplatform 21, and studs 22 are vertically secured to the spiders 20, saidstuds passing through the flanges 19 of the channel bars 17 and 18. Acoil spring 23 embraces each of the studs 22 between the spider 20 andthe channel bars 17 and 18, so that said spider is resilientlymaintained at a short distance above said channel bars.

A plurality of upper struts or ribs 24 and middle struts or ribs 25 areradially secured to the pole 10, the strut 11,241, and 25 being equal innumber and vertically positioned one above the other. Bearings 26 aresecured to the outerends of the struts 24, and

bearings 27 are secured to the outer end of the struts 25, said bearingsbeing adapted to slidably support rack bar 28 so that said rack bar isvertically positioned parallel to length so as to normally hold the end31 in contact with said rack teeth 29. A spider 32 is laterally securedto the lower end of the rack bar 28, and a cover press 88 similar to thebox platform 21 is secured to the lower side of said spider 82, saidcover press 33 being vertically positioned above said platform.

A pulley 34: is rotatably secured to the bearing 26. adjacent the rackbar 28, and a pulley 35 is rotatably securedto a bearing 36, aid bearingbeing secured to the strut 2 1 between the pole 10 and the pulley 341-.A rope or cable 37 having a weight 38 on one end passes over thepulleys'3ee and 85, the end of said cable opposite the weight 38 beingsecured to the lower end of the rack bar 28 by means of abolt or pin 39,said weight being adapted to normally hold the press 33 in its highestvertical position. vertical brace 40 is secured between each set ofstruts 11, 2 1, and 25, and a fork 41 is secured to the press 33, saidfork engaging the brace 40 so as to guide the 1novement of said press asthe rack bar 28 is reciprocated vertically. An oblique'brace 12 issecured to each set of struts 11,2 1, and 25 so as to prevent saidstruts from sagging under the weight of boxes 13 placed on the platforms21. A. cross head 44 is formed on'the upper end of each rack bar 28, anda press bar 4-5 is vertically positioned above the cross head 44, saidbar being slidably secured in a slide bearing 46 by means of elongatedtongues 417 formed on said bar 45 and engaging similarly shaped groovesin the bearing 46. The bearing 16 is supported by any suitable meanssuch as an over- I head beam 48 and a pulley 49 is-rotatably securedinbearings 50, said bearings being secured to a slide bearing 46 bybolts 51. A; cable 52 passes over the pulley 49, and

weight 53 is secured to one end of said cable, the other end of saidcable being secured by bolts 54 to the bar 45.

A horizontally extending bracket 55 is formed on the bar 45, and anoblique supporting brace 56 extends between the end of said bracket 55and the bar 45. A handle 57 'is suspended by a cable 58 from the outerend; of, the bracket 55, said handle being adapted to be lowered by aworkman so that the lower end of the bar 4-5 will engage the cross head5% thus pushing the rack bar 28 and the box'press 33 downwardly andfirmly into. engagement with the cover of the box as, said box press33remaining in contact wlth said cover Hill the glue thereof is dry. "Avertical post 59 is positioned acent the outer end of the struts 25, anda cam 60 having an upper arcuate surface 61 is secured to the post 59 bybolts 62, sald surface 61 hemp; adapted to engage the outer end of thepawl so as to release the pawl end 31 from the rack teeth 29, thuscausing the press 33 to move vertically under the ac tion of the weight38 so as to release the box cover when the glue is dry.

In operation a workman glues the covers of'the boxes, and places saidboxes on the platforms 21 one ata time. When each box is in place on theplatform, the handle. 57 is moved downwardly thus causing the box press33 to engage the cover of the box 43 under the action of the weight 38so that the box 43 may be removed by the workman with the glue of theboxcover dry and hard. The, apparatus is especially advantageous in thatboxes of various sizes may be glued and the springs 23 maintain the boxplatformQl resiliently so that the apparatus readily conforms itself toany slight irregularities in the boxes.

I would state in conclusion that while the illustrated example.constitutes a practical embodiment of my invention, I do not limit'myself strictly to the mechanical details hereinillustrated. sincemanifestly the same can be considerably varied without departure fromthe spirit of the invention as defined in'the appended claims.

Having thus described my invention, I
